1. How is SSH authentication handled ?
I don't know. Maybe through pam somehow? Can peruse ...
2. "dl:/etc/default/rsync" has this:
RSYNC_OPTS='--address=199.232.41.75'
Is this a left-over from an old server, or is it used for something?
That's a gnu.org address (cname for rev-c41-75.gnu.org), but there's no
forward dns A record for it now. I imagine it used to be dl's public
interface, when it also had a 10.x interface. Then it was necessary to
tell rsync to use the public interface.
So, I think the option can be removed. I wonder if rsync is logging
somewhere that it's being told to use a nonexistent interface now ...
thanks,
